Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a motor rotor, a motor and an air conditioner. The motor rotor comprises a rotating shaft sleeve ring, a plurality of iron cores that are disposed at the outer side of the rotating shaft sleeve ring and ordered in the annular manner. An inner opening and an installing groove are formed between two adjacent iron cores, wherein the installing groove is used for installing magnetic steel. A non-magnetically conductive connector is disposed between the rotating shaft sleeve ring and the plurality of the iron cores, in order to fixedly connect the rotating shaft sleeve ring with the plurality of the iron cores. The non-magnetically conductive connector is disposed between the rotating shaft sleeve ring and the plurality of the iron cores, and the magnetic steel disposed between adjacent iron cores are in abut connection with the non-magnetically conductive connector, so that the inner side of the magnetic steel is prevented from forming magnetic leakage through conduction of connection bridges at two sides of the magnetic steel, and then magnetic steel utilization of the motor rotor is facilitated.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a motor rotor, a motor and an air conditioner. Background technique [0002] At present, the fan in the air conditioner is generally driven by a motor. The motor includes a stator and a rotor. The collar is fixedly connected, and a mounting groove for the magnetic steel is formed between adjacent iron cores. [0003] However, when the magnetic steel is installed between two adjacent iron cores, the inner part of the magnetic steel will conduct through the connecting bridges on both sides of the magnetic steel to form magnetic flux leakage, thereby reducing the utilization rate of the magnetic steel. Contents of the invention [0004] The main purpose of the present invention is to provide a motor rotor, aiming to solve the problem of magnetic steel leakage of the motor rotor and improve the utilization rate of the magnetic steel. [0005] In order to achieve the abov...
